Gas Specific Gravity Meter May 2017 Micro Motion Gas Specific Gravity Meters Micro Motion Gas Specific Gravity Meters use proven Ni-Span-C vibrating cylinder technology to provide fast-response, precision gas specific gravity measurement over a wide operating range. These meters can be calibrated to directly measure specific gravity, molecular weight, relative density, and base density; and, can be configured for hydrogen purity, calorific value/btu and wobbe index. No additional calculation using temperature and pressure compensation is required. The Gas Specific Gravity Meter can be used in applications such as natural gas custody transfer, fuel gas combustion control and hydrogen purity monitoring. Application configurations You can preselect an application-specific configuration for your meter from a wide range of options. 6SHFLILF *UDYLW\ 0ROHFXODU :HLJKW &DORULILF 9DOXH %78 :REEH,QGH[ 5HODWLYH 'HQVLW\ + 3XULW\ /LQH 'HQVLW\ Integral transmitter Supports Time Period Signal (TPS), Analog (4-20 ma), HART, WirelessHART, and Modbus RS-485 communications.

SCROLL SELECT STATUS Gas Specific Gravity Meter May 2017 Operating principle Sample gas conditioning The gas to be measured is conditioned by an integral restriction orifice, reference chamber and pressure control diaphragm. After conditioning, the density of this gas is insensitive to changes in pressure (P), temperature (T), and compressibility (Z). The density of the gas is now only sensitive to changes in molecular weight. B C D A E A. Gas inlet (supply pressure) B. Restriction orifice C. Reference chamber D. Diaphragm E. Gas outlet Cylinder vibration A Ni-Span C cylinder is mounted inside a pressure-retaining assembly containing the process gas. The Ni-Span C cylinder is vibrated electro-magnetically at its natural frequency. Changes in sample gas composition and, thus density, which is now proportional to molecular weight, cause the natural frequency of the cylinder to change. A. Ni-Span C cylinder 4 www.emerson.com
